A collaborative research team from the Institute of Chemistry at the Chinese Academy of Sciences and the National University of Singapore has triumphantly developed a roll-to-roll nano-printing technology. This advancement facilitates the large-scale, cost-effective production of optical metamaterials. This breakthrough effectively tackles a significant hurdle in the practical deployment of this field, with the pertinent research findings published in the esteemed journal Nature. Optical metamaterials, known for their ability to 'manipulate light,' are heralded as a pivotal core technology for the forthcoming generation. Nevertheless, conventional preparation methods are prohibitively expensive, sluggish, and challenging to scale up for mass production.

To overcome these limitations, the research team creatively engineered multi-scale micro-nano structures and formulated roll-to-roll additive nano-printing equipment. This innovation has paved the way for low-cost, large-scale, and customized production. By harmonizing the principles of light manipulation, this technology unlocks fresh avenues for multi-scenario applications. Looking ahead, the team is poised to further develop sensing chips based on this technology, fostering its application across diverse domains and aiding China in securing a vanguard position in innovation within the field of micro-nano photonics.
